Re: [PATCH babeltrace 1/2] Added Python 3.0 or better requirement to the README file

[Jérémie Galarneau]

If I'm not mistaken, the scripts do work with Python 2.7. However,
maintaining this compatibility comes with a significant development
and testing overhead which I don't think brings that much value in the
end.

We're not talking about dropping support for tracing on RHEL here...
we're talking about Python bindings which are completely optional and
not part of the master branch. To me this is simply a case of handling
a dependency just like any other... a package exists for most users,
and RHEL users may have to install from source. I just don't see the
problem.

Anyway, RHEL/CentOS 6 does not even provide a Python 2.7 package...
Only Python 2.6 is officially supported[1].

Google can say what they want, RHEL 6 is still widely used (RHEL 5 is
still widely use...)

Personnally, it don't affect me much, since debian will probably switch
sooner or later, but seeing the number of request to have LTTng
supported on RHEL, it might be something to think about.

For our python scripts to work, do we need python 3 to be default ?

About RHEL6, interesting links:

http://www.muktware.com/5203/google-says-red-hat-enterprise-linux-6-obsolete

Something to think about ;)

Jérémie: how much extra effort would be required to support python 2.7+
(only) as well as python 3 ?

Just to name 2: Centos/RHEL 6.x and Debian.

CentOS/RHEL does not have a Python 3 package

Debian is default to 2.7, can install python3, but will potentially
breaks apps that rely on python 2 if I set python 3 to default.

[Mathieu Desnoyers]

Hi Yannick,

Please list all the distro and distro versions you care about that still
ship with python 2.7 by default today, along with the time-frame for
which they are going to still be supported by the vendors, and whether
those distributions allow users to install python 3.0 side-by-side with
2.7 or not.

Thanks,

Mathieu

Re: [PATCH babeltrace 1/2] Added Python 3.0 or better requirement to the README file

[Jérémie Galarneau]

Although I agree it can prove to be an inconvenience for some users,
most distributions provide a Python 3 package at this point.

The reasoning is that since these bindings are still in development
and won't be integrated into the master branch for some time, the
effort needed to develop and test them while targeting two versions of
Python is hard to justify.

My main concern is that 2.7 is still the default version for many linux
distribution, so it might be early to drop 2.7 support.

As for as I know, the bindings do work with Python 2.7.
However, we have decided to no longer explicitly support older
versions of Python in order to make the bindings, along with future
developments, easily maintainable.
